| In this study, elicited estimates of farmers' subjective beliefs about the mean and variance of wheat variety yields were used to test propositions about Bayesian learning developed in the recent literature on innovation adoption. A series of empirical tests of the Bayesian adoption model were conducted using beliefs elicited from farm surveys conducted in 1982, 1983 and 1984. The results of the analysis neither confirm nor reject the Bayesian approach as a model of how farmers revise subjective beliefs, but do raise serious doubts about its realism, and suggest some issues requiring further investigation. Shortcomings in the elicitation techniques are discussed and the assumptions of the Bayesian model are reviewed. |

| Fruit flies are recognised as one of the major pests of fruit and vegetable crops worldwide. Potential benefits from fruit fly research include biosecurity benefits from better quarantine surveillance that reduces the costs of an incursion by a damaging exotic pest fruit fly; market access benefits by enabling new fruit exports; and field control benefits from better crop management. The Australian Centre for International Agricultural Research (ACIAR)’s investment in fruitfly research goes back some 25 years to an initial project in Malaysia. Since that time, ACIAR’s continued investment has funded a total of 18 projects ranging across several areas of fruit-fly research, and covering Malaysia, Thailand, Philippines, Fiji Islands, Samoa, Tonga, Cook... |

| A prevalent problem in shared fisheries is competition between commercial and recreational fishers for access to a resource that is subject to increasing utilisation pressure. For most shared fisheries in New Zealand, the commercial sector is efficiently managed with a regime of individual transferable quota (ITQ), but the recreational fishing is only minimally managed. A model is developed that can be used to explore the size of the total allowable catch (TAC) that is both sustainable AND maximises the value to the NZ economy of the combined commercial and recreational catch when the commercial catch is regulated via a total allowable commercial catch (TACC) while the recreational catch (RC) is self regulating. Determinants of the optimal catch allocation... |

| Conjoint measurement was used to determine consumer preference for fresh pork produced with genetically engineered porcine somatotropin (pST). A preference model was constructed based on three pork attributes, degree of fat reduction, price, and production technology, which allowed for interactions between attributes to be estimated. Interview surveys were used to collect data in several shopping centres in three Australian cities. Respondents generally preferred leaner pST-supplemented pork, but only at fat reduction levels greater than those possible with conventionally produced pork, and at competitive prices. |

| Some hypotheses about the timing of farmers becoming aware of an innovation and the subsequent decision to use that innovation are derived from a recently developed, decision-theoretic model of the adoption process. They are tested using empirical evidence on the time taken by early adopters of trace element fertilisers in S.A. to discover and decide to use this innovation. The central role of information search in the adoption process is emphasised and it is postulated that various distance measures provide a useful measure of information availability and reliability. The results of the empirical analysis are consistent with the hypothesised relationships. Another finding is the importance of distinguishing between early adopters who are genuinely... |

| Perceptions are known to play an important role in the innovation adoption decision. Once influential perceptions have been identified, there is the potential for information to influence adoption by changing these perceptions. In this paper, the influence of an extension workshop targeting grain growers’ perceptions known to be associated with the adoption of integrated weed management and herbicide resistance management has been measured using regression analysis. Consistent with a Bayesian learning framework, the greatest influence on grower perceptions and intended adoption behaviour was observed where information could be delivered with a high degree of certainty and validity. |

| Fluctuating annual harvest volumes create a peak load problem in the provision of grain storage capacity. There are a number of technologies for handling and storing grain, ranging from capital intensive to labour intensive methods. Optimal provision of grain storage capacity can therefore be analysed in the framework of the conventional peak load pricing model. An investment model of grain storage is outlined and the optimal technology choices are determined according to simple investment roles. Capacity of the more capital intensive storage types should be only provided if the extra capital cost is justified by the saving in operating costs, which depends on the expected utilisation of storage. Some level of supply failure is justifiable. An examination... |

| As private plant breeding replaces public programs, the efficient provision and utilisation of key enabling technologies for crop breeding, which are largely knowledge based and provide the foundation for variety improvement, might be at risk. Typically, such inputs are non‐rival in use and are therefore termed essential plant breeding infrastructure (EPBI). Specific threats include the possibility of wasteful duplication in production, under‐production, under‐utilisation of produced EPBI because of price rationing, and anticompetitive outcomes in plant breeding and downstream markets. The likely level of under‐investment in hypothetical molecular‐marker technology by a profit‐maximising monopoly producer, charging uniform prices for access, is analysed... |

| In the absence of some form of government intervention, knowledge is a classic public good which will be under-produced because of lack of price excludability. Government intervention may take the form of establishing intellectual property rights, or other means of shielding knowledge-based innovations from imitation or copying. Such intervention offers the prospect of 'privatising' the production of knowledge in the sense that a certain level of private knowledge production may become profitable if producers can appropriate at least part of the benefits of R&D. However, publicly funded R&D or extension still can 'crowd out' private knowledge production by charging lower prices. The principal finding of this study is that such 'crowding out'... |
